This would be interesting if idea is turned around on existing information on youtube instead of freshly gathering information. Since there is lot of information on youtube to play with.

Pick 'x' 'qualified' videos based on speaker credentials (eg: Sam Altman, Peter Theil, Founders, VCs, Partners etc). Most of these youtube videos take on Q&A or talk types. You can make a 'good' catalogue of all relevant questions asked by interviewer and link to answers provided by each interviewer.
